FLY EVO3 chassis Porsche 917k for RT3 Motor Mounts

The EVO3 chassis that transforms your Porsche 917k into a real competition car

When an iconic body like the Porsche 917k deserves more than the standard chassis, Scaleauto responds with this FLY EVO3 chassis (ref. SC-9100E). Specifically designed to accept RT3 motor mounts, it is the piece that makes the difference between rolling and truly competing.

Function and performance

The purpose of this chassis is clear: to replace the original base of FLY models with Porsche 917k body and open the door to the Scaleauto tuning ecosystem. By integrating with the RT3 mounts, the assembly gains controlled flexibility and allows for precise adjustment of the chassis tilt, resulting in a much more efficient weight distribution when entering and exiting corners.

The internal geometry is optimised to lower the centre of gravity, reduce roll and improve rear traction without compromising stability on high-speed straights. The result is a more predictable car with greater fine-tuning margin.

Compatibility and motor configurations

One of the most notable advantages of this chassis is its versatility in motor positioning thanks to compatibility with RT3 mounts. Depending on the RT3 mount installed, it supports three configurations:

• Inline: longitudinal motor, in line with the rear axle. Lowers the centre of gravity even further and is common in high-level competition.
• Sidewinder: transverse motor, parallel to the rear axle. Offers a good balance between torque and mass distribution.
• Anglewinder: angled motor relative to the rear axle. Combines compactness and good performance on technical circuits.

This flexibility allows for adapting the mechanics to the championship regulations or the driver's personal preferences without the need to change chassis.

Assembly and preparation

The chassis incorporates specific mounting points for the Porsche 917k body, facilitating a clean and secure anchor. The adjustment of the front axle height is done using allen screws, allowing fine-tuning of the geometry according to the type of circuit and track conditions.

The technical plastic material used absorbs impacts well without deforming, which is particularly relevant in long training sessions or club competitions where incidents are inevitable.

Ideal for…

• Drivers who already own a FLY Porsche 917k body and want to elevate their preparation level.
• Competitors looking to incorporate Scaleauto's RT3 mount system into a classic chassis.
• Enthusiasts who want to experiment with different motor configurations without investing in a new car.
• Clubs and drivers in regulated categories that allow the use of alternative chassis with original bodywork.

Points to consider

This chassis is designed for FLY Porsche 917k bodies. Before purchasing, it is advisable to verify that the anchoring points of your body are compatible. The RT3 motor mounts are not included with the chassis and must be purchased separately. Likewise, the motor, transmission, and running accessories are not part of this item.

Frequently asked questions

Are the RT3 mounts included with the SC-9100E chassis?

No. The FLY EVO3 SC-9100E chassis is compatible with Scaleauto's RT3 motor mounts, but these are sold separately. They must be purchased separately to complete the installation.

Which bodies is this chassis compatible with?

It is specifically designed for FLY Porsche 917k bodies. Compatibility with bodies from other manufacturers or other versions of the 917 is not guaranteed.

What motor configuration is most recommended with this chassis?

It depends on the circuit and the regulations. The inline configuration tends to offer the lowest centre of gravity and greater traction, being common in technical competition. The sidewinder is a balanced option for general use. The final choice will depend on the RT3 mount that is installed.

Is it suitable for official competition?

That depends on the specific regulations of the championship or club. The EVO3 chassis is designed for competitive use, but it is always advisable to check with the organisation if the use of alternative chassis with the original body is permitted.

Does it work on SPORT track and universal track?

The performance of the chassis on track is independent of the type of track. What must be adapted are the guide and braids, which must be compatible with the track system used (SPORT track for Scaleauto and Slot.it; universal track for Scalextric and Ninco, among others).

Does it include motor, tyres or other components?

No. The SC-9100E is only the chassis. The motor, transmission, tyres, guide, braids, and any other mechanical components must be mounted separately.

The Scaleauto FLY EVO3 chassis (ref. SC-9100E) is a high-performance replacement chassis for Porsche 917k bodies, engineered to accept RT3 motor mounts. Compatible with inline, sidewinder and anglewinder motor configurations, it delivers improved roll centre geometry, lower centre of gravity and precise front axle height adjustment — making it a go-to upgrade for slot car racing enthusiasts and club competitors looking to maximise their classic bodyshell's potential.
